The kit relocates both the upper and lower ball joints to add caster for better steering feel and high speed stability, with a designed caster range of 5 to 7 degrees. The spindle pin location stays in the stock position so fender clearance remains like factory. The upper A-arms use chromoly offset cross shafts to reduce the number of shims needed when setting camber, and include a pancake style polyurethane bump stop and a high quality ball joint. The heavy duty lower spring bucket accepts factory and aftermarket coil springs as well as popular hybrid coilover units. Laser cut UMI reinforcement plates add strength and a clean appearance. UMI double shear sway bar end links are included and work with the UMI 4035 sway bar and most aftermarket stock eyelet style sway bars. This kit is finished in UMI red powder coat and is also offered in gloss black. These A-arms are designed, manufactured, and raced in the USA in Philipsburg, Pennsylvania.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Front tubular upper and lower A-arm kit\u003c\/li\u003e\n\u003cli\u003eBall joint relocation: upper and lower, 5 to 7 degree caster range\u003c\/li\u003e\n\u003cli\u003eUpper cross shafts: chromoly, offset\u003c\/li\u003e\n\u003cli\u003eBushings: polyurethane and aluminum\u003c\/li\u003e\n\u003cli\u003eIncludes: polyurethane bump stops, ball joints, double shear sway bar end links, and hardware\u003c\/li\u003e\n\u003cli\u003eSpring bucket: heavy duty, accepts factory, aftermarket, and hybrid coilover springs\u003c\/li\u003e\n\u003cli\u003eMaterial: steel\u003c\/li\u003e\n\u003cli\u003eFinish: UMI red powder coat\u003c\/li\u003e\n\u003cli\u003eSold as: Kit\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 265153-R\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1970 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1971 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1972 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1973 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1974 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1975 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1976 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1977 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1978 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1979 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1980 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1981 Chevrolet Camaro\u003c\/li\u003e\n\u003cli\u003e1970 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1971 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1972 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1973 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1974 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1975 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1976 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1977 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1978 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1979 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1980 Pontiac Firebird\u003c\/li\u003e\n\u003cli\u003e1981 Pontiac Firebird\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does this A-arm kit fit?\u003c\/h5\u003e\u003cp\u003eIt fits 1970 to 1981 GM second generation F-body cars, including the Chevrolet Camaro and Pontiac Firebird.\u003c\/p\u003e\u003ch5\u003eHow much caster does this kit add?\u003c\/h5\u003e\u003cp\u003eThe upper and lower ball joints are relocated to provide a designed caster range of 5 to 7 degrees, while the spindle pin location stays in the stock position so fender clearance remains like factory.\u003c\/p\u003e\u003ch5\u003eWhat is included in the kit?\u003c\/h5\u003e\u003cp\u003eThe kit includes tubular upper and lower A-arms with polyurethane and aluminum bushings, polyurethane bump stops, ball joints, UMI double shear sway bar end links, and mounting hardware.\u003c\/p\u003e\u003ch5\u003eWill these work with my existing springs?\u003c\/h5\u003e\u003cp\u003eThe heavy duty lower spring buckets accept factory and aftermarket coil springs as well as popular hybrid coilover units.\u003c\/p\u003e\u003ch5\u003eWhat is the difference between the red and black versions?\u003c\/h5\u003e\u003cp\u003eThe two are identical except for powder coat color.
